PRELIMINARY POSITIONOF THE RCC CAs ON THE AGENDA ITEMS

OF THE WORLD RADIOCOMMUNICATION CONFERENCE

2012

2

1.1

• To consider and take appropriate action on requests from administrations to delete their country footnotes or to have their country name deleted from footnotes, if no longer required,taking into account Resolution 26 (Rev.WRC-07).

• RCC CAs support the ITU-R activities towards the worldwide harmonization of the radio frequency spectrum usage by reducing the number of national footnotes to Article 5 of the Radio Regulations.

1.2• Taking into account the ITU-R studies carried out in accordance with Resolution 951 (Rev.WRC-

07), to take appropriate action with a view to enhancing the international regulatory framework.

• Convergence of terrestrial services• RCC CAs are of the view that current provisions of the Radio Regulations do not limit the use of• different applications in terrestrial services (fixed and mobile).• (see also Method A1 of the draft CPM Report)

• Convergence of satellite services• In relation to convergence of satellite services, RCC CAs believe that modifications of the Radio

Regulations provisions are not reasonable. The current procedures of the Radio Regulations provide the necessary flexibility to the administrations in terms of choice of satellite service applications in the frame of existing frequency bands allocations.

• General principles of frequency bands allocation• 1. RCC CAs support that studies on improvement of international regulatory framework and

principles of allocation of the frequency bands for radio services should be finalized at WRC-12.• 2. RCC CAs believe that current regulatory framework provide sufficient flexibility and does not

prevent the implementation of new technologies.

• (see also Method B1 of the draft CPM Report)

1.3• To consider spectrum requirements and possible regulatory actions, including allocations, in• order to support the safe operation of unmanned aircraft systems (UAS), based on the results of• ITU-R studies, in accordance with Resolution 421 (WRC-07).

• 1. RCC CAs are of the view that to ensure the safe flight operation of UAS in non-segregated airspace the existing and/or new allocations to AMS(R)S (for satellite component of UAS), as well as AM(R)S and ARNS (for terrestrial component of UAS) should be used provided that compatibility with incumbent services is ensured.

• 2. RCC CAs are of opinion that the development of appropriate international ICAO standards for systems operating in AMS(R)S, AM(R)S and ARNS shall be mandatory since these services are intended for provision of safety and regularity of flights including international routes of civil aviation.

• 3. RCC CAs do not support consideration of the bands 960-1164 MHz, 1525-1559 MHz, 1610- 1660.5 MHz, 5000-5030 MHz and 15.4-15.7 GHz as candidate ones for the safe flight operation of UAS.

• 4. RCC CAs do not support any proposals to modify the Radio regulations with respect to frequency bands for which studies under WRC-12 AI 1.3 have not yet been completed.

ACP WG-F

1.4

• To consider, based on the results of ITU-R studies, any further regulatory measures to facilitate introduction of new aeronautical mobile (R) service (AM(R)S) systems in the bands 112-117.975 MHz, 960-1164 MHz and 5000-5030 MHz in accordance with Resolutions 413 (Rev.WRC-07), 417 (WRC-07) and 420 (WRC-07).

• Resolution 413 (Rev. WRC-07)• RCC CAs do no object to the usage of the frequency band 112 – 117.975 MHz by

AM(R)S systems since the conducted studies showed the possibility of its compatibility with the analogue broadcasting systems operating in the bands below 108 MHz. The AM(R)S usage should be limited by the systems which should operate in accordance with the acknowledged international aviation standards.

• RCC CAs support the appropriate modifications of Resolution 413.• (see also Method A of the draft CPM Report)• Resolution 417 (WRC-07)

• 1. RCC CAs are of the view that protection of ARNS stations from systems of AM(R)S in the frequency band 960-1164 MHz, as well as compatibility of AM(R)S systems in the band 960-1164 МHz with RNSS stations operating in the adjacent band 1164-1215 МHz shall be ensured.

1.4

• 2. RCC CAs support the modification of Resolution 417 (Rev.WRC-12) with respect of the conditions of protection of ARNS operating in the frequency band 960 – 1164 MHz and the stations of RNSS operating in the adjacent frequency bands 1164 – 1215 MHz from the interference caused by the stations of AM(R)S operating in the frequency band 960 – 1164 MHz.

• (see also Method B1 of the draft CPM Report).

• Resolution 420 (WRC-07)• RCC CAs do not object the allocation of the frequency band 5 000 –

5 010 MHz to AM(R)S provided that the compatibility with the existing radio services in this and adjacent frequency bands under adopted restrictions is ensured.

• (see also Method C2 of the draft CPM Report)

ACP WG-F

1.5

• To consider worldwide/regional harmonization of spectrum for electronic news gathering• (ENG), taking into account the results of ITU-R studies, in accordance with Resolution 954• (WRC-07).

• RCC CAs consider that:• - spectrum harmonization for ENG systems should be conducted in the

frequency bands already allocated for the services on the worldwide or regional basis and appropriate for the use of ENG;

• - when considering the spectrum harmonization for ENG the protection of other applications used by administrations in the considered frequency bands should be ensured;

• - when considering the spectrum harmonization for ENG it is necessary to take into account the existence of effective encoding and audiovisual data compression methods. At the same time it is necessary to take into account both the existing technologies of increasing the efficiency of channel resource usage and the advanced audiovisual data transmitting technologies taking into account their implementation and maintenance practice.

1.7

• To consider the results of ITU-R studies in accordance with Resolution 222 (Rev.WRC-07) in order to ensure long-term spectrum availability and access to spectrum necessary to meet requirements for the aeronautical mobile-satellite (R) service, and to take appropriate action on this subject, while retaining unchanged the generic allocation to the mobile-satellite service in the bands 1 525-1 559 MHz and 1 626.5-1 660.5 MHz.

• 1. Ensuring guaranteed long-term access of AMS(R)S to the bands 1525 – 1559/1626.5 – 1660.5 MHz should not result in the change of the existing general allocation of these frequency bands to the MSS or impose constraints on existing MSS systems operated in accordance with the RR provisions.

• 2. Existing regulatory provisions defining the AMS(R)S status (RR No. 5.357A) give priority when satisfying existing AMS(R)S spectrum requirements for communications with priority 1 to 6 as per Article 44 in the bands 1545 – 1555 / 1646.5 – 1656.5 MHz. Therefore current regulatory provisions defining the existing usage of the bands 1545 – 1555 / 1646.5 – 1656.5 MHz for AMS(R)S, in particular No. 5.357A, should remain unchanged (see also Method C of the draft CPM Report).

• 3. To satisfy future spectrum requirements for AMS(R)S it is expedient to consider other existing AMS(R)S allocations (for example in the band 5 GHz) or new AMS(R)S allocations exclusively for transmitting messages with priority 1 to 6 as per Article 44 since realization of future AMS(R)S spectrum requirements in the bands 1545 – 1555 / 1646.5 – 1656.5 MHz (according to RR No. 5.357A) will inevitably impose undue constrains on the existing MSS systems (taking into account that bands 1525 – 1559 / 1626.5 – 1660.5 MHz are extremely in demand and limited).

1.9• To revise frequencies and channelling arrangements of Appendix 17 to the Radio Regulations, in

accordance with Resolution 351 (Rev.WRC-07), in order to implement new digital technologies for the maritime mobile service.

• RCC CAs support revision of the Appendix 17 of the Radio Regulations according to Resolution 351 (Rev.WRC-07) if the following requirements are satisfied:

• - the implementation of changes of Appendix 17 requires a transition period (till 01.01.2015);

• - conditions and channelling arrangements for telephony in Appendix 17 and Appendix 25

• should be retained;• - distress and safety frequencies should be retained;• - in the frequency bands assigned to the MMS stations with application of digital

technologies administrations can assign frequencies to the stations for Morse telegraphy subject to the condition that no harmful interference is caused to, and no protection is claimed from the stations using digital technologies.

• - in the frequency bands assigned to the stations for Narrow-Band Direct-Printing (NBDP) during the transition period the priority of NBDP over digital technologies is retained. After the transition period stations using NBDP can be used subject to the condition that no harmful interference is caused to, and no protection is claimed from the stations using digital technologies (see also section 1/1.9/5 of the draft CPM Report)

1.12

• To protect the primary services in the band 37-38 GHz from interference resulting from aeronautical mobile service operations, taking into account the results of ITU-R studies, in accordance with Resolution 754 (WRC-07).

• RCC CAs are in favour of the restriction of the mobile service allocation in the band 37-38 GHz to land- and maritime mobile services only (see also Method A of the draft CPM Report).

ACP WG-F

1.14

• To consider requirements for new applications in the radiolocation service and review allocations or regulatory provisions for implementation of the radiolocation service in the range 30-300 MHz, in accordance with Resolution 611 (WRC-07).

• RCC CAs propose to allocate the frequency band 154-156 MHz to the radiolocation service on a primary basis providing necessary protection for the FS and MS systems and limiting application of this service by detection of space objects (see also Method A of the draft CPM Report).

ACP WG-F

12

1.15• To consider possible allocations in the range 3-50 MHz to the radiolocation service for• oceanographic radar applications, taking into account the results of ITU R studies, in accordance• with Resolution 612 (WRC 07).

• 1. RCC CAs do not object to the allocation to the radiolocation service of certain frequency bands

• up to 600 kHz each in the frequency band 3-50 MHz providing compatibility with other services• allocated in this band.• 2. RCC CAs are of the view that it is possible to allocate to the radiolocation service on the• primary basis a number of frequency bands in the range 3 – 44 MHz (3155-3200 kHz, 4438-4650• kHz, 5060-5450 kHz, 7450-8100 kHz, 9040-9400 kHz, 9900-9995 kHz, 12100-12230 kHz,• 13410-13570 kHz, 13870-14000 kHz, 14350-14990 kHz, 15800-16350 kHz, 22855-23200 kHz,• 24000-24890 kHz, 25010-25070 kHz, 25210-25550 kHz, 26175-27500 kHz, 39-39.986 MHz,• 40.02-40.98 MHz and 41.015-44.0 MHz), limited to the oceanographic radar applications subject

to• the restriction of e.i.r.p to 25 dBW and agreement to its usage from the concerned

Administrations• (see also Method A of the draft CPM Report).• 3. RCC CAs are of the view that the frequency bands in the range 44 – 47.5 MHz should not be• allocated to the radiolocation service for oceanographic radar applications.

ACP WG-F

1.19• To consider regulatory measures and their relevance, in order to enable the introduction of• software-defined radio and cognitive radio systems, based on the results of ITU-R studies, in• accordance with Resolution 956 (WRC-07).

• 1. RCC CAs are of the view that cognitive radio systems (CRS) and software defined radio (SDR) are the technologies used by stations of some radiocommunication services. Such use should be in accordance with the provisions of the Radio Regulations specified for these services for the relevant frequency bands. RCC CAs consider that there is no need in changing Articles of the Radio Regulations for the use of CRS and SDR

• 2. RCC CAs are of the view that decisions on the possibility to introduce these technologies (SDR and CRS) and evaluation of necessity to change regulatory provisions should be taken on the basis of studies on measures which could provide protection of the stations already used within existing allocations.

• 3. RCC CAs support the development of WRC Resolution containing guidance on further ITU-R studies on deployment and use of cognitive radio systems

• 4. RCC CAs do not support new Agenda Item for WRC-16 on CRS.• 5. RCC considers that during the studies of implementation and use of the cognitive

radio systems it is necessary to study the cases when CRS is used in the services shared with space services (spaceto- Earth), radiodetermination service, the services using passive sensors (radio astronomy service, EESS, SRS) and safety services due to increase of possibility of harmful interferences

1.21

• To consider a primary allocation to the radiolocation service in the band 15.4-15.7 GHz, taking into account the results of ITU-R studies, in accordance with Resolution 614 (WRC-07).

• RCC CAs consider that additional allocation in the band 15.4-15.7 GHz to the radiolocation service is possible on condition of protecting stations perating within existing allocations in the affected frequency bands.

ACP WG-F

15

1.22

• To examine the effect of emissions from short-range devices on radiocommunication services,

• in accordance with Resolution 953 (WRC-07).

• 1. RCC supports the continuation of ITU-R studies in accordance with the relevant WRC Resolution for SRD on impacts of emissions from short-range devices (SRD) on radiocommunication services for purpose of global of regional harmonization of the frequency bands and technical conditions of work of SRD which can be moved abroad and create harmful interference to radiocommunication services.

• 2. RCC CAs believe that for exclusion of impact of emissions from some SRD types (for example, RFID) on radio services, the development and application of an individual ITU-R Recommendation (s) on technical characteristics and conditions of these SRD types use is needed.

• (see also Method B of the draft CPM Report).

ACP WG-F

16

1.23

• To consider an allocation of about 15 kHz in parts of the band 415-526.5 kHz to the amateur service on a secondary basis, taking into account the need to protect existing services.

• 1. RCC CAs consider that additional allocation of a frequency band to the amateur service on a secondary basis in the band 415 – 526.5 kHz should be made on condition of providing protection of services to which this band is currently allocated including frequency assignments in the Plans of GE-85 Agreement for МMS and ARNS.

• 2. RCC CAs are of the view that Method D is appropriate for the future discussions on this Agenda Item.

ACP WG-F

17

1.25• To consider possible additional allocations to the mobile-satellite service, in

accordance with• Resolution 231 (WRC 07).

• RCC CAs consider that:

• 1. The need for additional allocations to the mobile-satellite service (MSS) should be justified by relative requirements which could not be satisfied through the existing MSS allocations;

• 2. New allocations to the MSS shall only be made in those bands of the range 4 GHz to 16 GHz where adequate protection of the incumbent terrestrial and space services is ensured, and MSS will not claim protection from potential interference from existing and future stations of the incumbent services;

• 3. Taking into account the results of sharing studies, RCC CAs are of the view that:• - sharing MSS with incumbent services in the frequency bands 7055 – 7250 MHz

(space to Earth), 8400-8500 MHz (Earth to space) and 15.43-15.63 GHz (Earth to space) is very difficult, therefore these bands cannot be allocated to MSS;

• - feasibility of sharing MSS with incumbent services in the frequency bands 5150-5250 MHz (space to Earth), 10.5 -10.6 GHz (space to Earth) and 13.25-13.4 GHz (space to Earth) is still not fully studied therefore further detailed investigations are required;

• - making allocations to the MSS in other bands in the range 4 GHz to 16 GHz are not advisable.
